Which plan should I select? 1900 sq ft home

I was thinking 200, but would do the 500 for the first year since they are running a deal right now. Customer service recommended Fiber 1g. A little less than 1900 Sq ft (including yard and all that). Normal devices, like computer, TV, phone, etc. No gaming, and just 1 user. I feel like I don't need Fiber 1g since it is just 1 user most of the time, but I didn't take the size of my home into consideration. Thoughts?
